Hi,I don't know if it is caused by AS2004, but I have used it now 2 times and on both occaisions during approach phase the weather went bezerk for a small period of time. I guess during about 60 seconds.As you can see in the picture below, my IAS suddenly dropped to 0.http://forums.avsim.net/user_files/54572.jpgAlso after the IAS was normal agin after appr. 60 seconds, I experienced very heavy turbulance. Is this caused by AS2004 or something else?Take care,Egbert

Were you in cloud, and were the temps below freezing, and did you have the pitot heat on? If the first 2 were yes, and the last one no, then make sure you turn the pitot heat on before takeoff and leave it on for the flight. If all 3 were yes, make sure you turn your de-ice equipment on. That should fix your problem. If it is AS2004, then it is making things more realistic for you, not less :-).

Also make sure icing is turned off in FSUIPC.Hope this helps,JimActiveSky Support

Hi,Icing may be the issue, will check next time.What I didn't mentioned (sorry :-) ):I was running AS2004 over WideFS and I got a messagebox in AS2004, sometime like 'Temp data issue EFRO, skipping....'EFRO was the airport I was approach at that moment.Egbert
